Abstract

One form of magnetic printing utilizes a magnetizable medium, such as magnetic tape, upon which a magnetic latent image is formed. This magnetic latent image is made visible with the use of a dry toner containing small magnetic particles commonly referred to as monocomponent toner. The visible image is then transferred to paper and fixed with methods commonly known in the electrophotographic printing art. A critical element of this printing process is the effective toner mass per unit area deposited in the solid areas of an image. For both magnetic printing and electrophotography, this parameter is critical to maintaining print quality for printing characteristics, such as dark reflectance and line width.
